I am growing some from seed in pots.
Most of them are about 3 inches high now - but some of the leaves have
yellowish streaks in them,

I have looked on web and cannot find anything definitive. I sowed them in
ordinary compost and have not fed them at all.

???

Streaks meaning wiggly lines? They are prone to leaf mining caterpillars,
although it's early in the year for them I think.
